The Float.minFloat function returns the smallest nonzero single-precision
floating-point number that is supported by the browser.

The companion Float.maxFloat function returns the maximum single-precision
floating-point number that is supported by the browser.

If the browser does not support floating-point arithmetic operations,
then the browser will not recognize the Float Library, nor any
of the member functions. In this case, the Float.minFloat function
returns invalid.
